Low Rpm High Efficiency Biomass Gas Biogas Syngas Power Generator

Low Rpm High Efficiency Biomass Gas Biogas Syngas Power Generator

Syngas-biomass generations are driven by low speed 300 series engines, the gas fuel can be generated from gasification of MSW, woodchips, sawdusts, rice husks, straws, coconut shells, coal gas, coking gas, coke oven gas and pyrolysis gas etc. Low Speed 300 engines are specially designed for syngas as fuel, with remarkable features of low speed, big cylinder, big displacement, naturally aspirated and strong resistance ability against the TAR, highly reliable, durable, the overhaul can reachover 60000 hours.

Customer Benefits for Syngas Engines

• Cylinders Structure in Line & Upright & Concise Layout, which means simple, easy and low cost in operation & maintenance. Engine-Overhaul can be handled at user's site.

• Large cylinder (300mm), long stroke, low speed and big displacement 215L and 242L, which means big reserve power capacity and constant power output.

• Low engine speed at 500 or 600rpm, which means high reliability for continuous operation, sufficient combustion, low exhaust gas temperature and high heat efficiency.

• Naturally aspirated (no turbocharger and Intercooler), which means low failure rate and minimum downtime (TAR in syngas always block and damage turbocharger and intercooler).

• Internal mixing system (for high hydrogen gas over 15%), gas and air intake separately, then mixed in combustion room, which means no risk of backfire and cylinder knocking.

• Strong treatment and resistance ability against TAR, long term trouble free operation. TAR always raises problems of pipeline-blocking, cylinder-pollution and spark plug-jamming etc.

• Compressed Air Starting System, smooth starting, high success rate and easy for maintenance.

• Open Cooling System, adopting plate-type heat exchanger, high efficiency and easy for scale-removal.

• Dismountable intake-valve-box, which means can clean TAR easily and conveniently (no need disassembling of cylinder head).

• Low-speed engine makes the noise lower. The maximum noise ≤100dB. Through silencer, the noise will be ≤70dB.

• Low speed means low components wearing, namely lower cost in spare parts replacement and long life span.

• Long Overhaul Time of 60,000 hours and lifecycle of 20-25 years, which ensure sustainable financial rewards of power plant.

 Applicable Gas Fuels

• Biomass from MSW, Woodchips, Sawdust, Straw, Rice husks, Nut-shells, and Chicken manure etc.

• Industrial tail gas & refinery gas, such as coal gas, coking gas, semi-coke gas, coke oven gas, oilshell tail gas, carbide tail gas, ferrochromium tail gas, yellow phosphorus tail gas, producer gas and paralysis gas etc.
